Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475654, here are decompositions:

31 + 31475623 = 31475654
43 + 31475611 = 31475654
73 + 31475581 = 31475654
163 + 31475491 = 31475654
211 + 31475443 = 31475654
283 + 31475371 = 31475654
313 + 31475341 = 31475654
337 + 31475317 = 31475654

Showing the first eight; more decompositions exist.
